M.a. Ford. 27825000B Square End Mill 1/4 in 5 Flute Carbide

Product Description

The M.A. FORD. 27825000B is a 5-flute, single-end square end mill engineered for precision milling in demanding applications. Built from micrograin solid carbide and coated with AlCrN (aluminum chromium nitride), it handles high-heat, high-speed cutting operations where tool life and surface finish matter. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With a 1/4-inch mill diameter, 3/8-inch length of cut, and 2-inch overall length, this tool is sized for standard short-reach work in ferrous and non-ferrous materials. Variable index flute spacing helps suppress chatter during aggressive cuts.

This end mill is suited for milling operations in job shops, production machining environments, and tool rooms. The 1/4-inch shank diameter fits standard ER and milling chucks commonly used in CNC machining centers and manual knee mills. The AlCrN coating extends tool life in hardened steels, stainless alloys, and cast iron by providing thermal and oxidation resistance at elevated cutting temperatures. Machinists and CNC operators working with tight tolerances and fine surface finishes will find the 5-flute geometry and variable index design particularly effective at higher feed rates.

Key Features

• Micrograin solid carbide substrate for hardness and wear resistance
• AlCrN coating provides thermal protection and extended tool life in ferrous materials
• 40-degree right-hand helical flutes promote chip evacuation and reduce cutting pressure
• Variable index flute spacing reduces harmonic chatter during aggressive milling passes
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Single-end configuration with right-hand cutting direction

Compatibility

Designed as a standard short-length replacement square end mill for 1/4-inch shank ER collets and milling chuck toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum recommended insertion depth for the toolholder being used, and verify runout with a dial indicator before starting a cut. Consult the toolholder manufacturer's torque specifications when tightening collet nuts or end mill holders.
